macOS has no D-Bus/MPRIS: the audio engine is what the OS media UI talks to. mpv's Cocoa backend registers with MPRemoteCommandCenter and MPNowPlayingInfoCenter, so it already publishes the live ICY title and receives the media keys. Add a platform-neutral media session (mediasession.py) so the app keeps a single interface: MprisService on D-Bus platforms, NowPlayingSession on macOS. Map mpv's NEXT/PREV/PLAY/PLAYONLY/PAUSEONLY/STOP keys onto script-messages and read them back as client-message IPC events, so the hardware media keys and Control Center drive the TUI (station changes, play/pause/stop) instead of fighting it. --no-mpris (now also --no-media) disables the media keys too. macOS-only mpv options are gated on sys.platform so the Linux command line is unchanged; mpv aborts on unknown flags.
